Inshaving position the tracer pin 51 of the blade carrier 20 is arrestedand secured between the two corrugations 85 and 35 of cam plate 62.

The support 53 for the lower housing pad 22 is semibar-rel shapedpositioned and mounted between the side walls 25 and 26 `of the bladecarrier 20 on shaft 27, and secured by pin 54. The arms 55 and 56 `areprojected frontwardly as integral members of the upper side portion ofthe support 53 to provide support-for nod 57 which is provided, to carry[and position the tubular front guard 58 between said arms in iront of,and below the blade edge 17.

The lower honing pad 22 and the 4upper honing pad 23, havingapproximately the length of the razor blade, are provided with layens 77and '78 of abrasive material. The lower pad 22 is located between theside walls 25 and 26 of the blade carrier 20', and is mounted on suppont53. 'Ilhe ,upper honing pad 23 is positioned between the side walls 15and `16 of housing 13 in common plan with the lower pad 22, :and ismounted on the inner surface 61 of base wall 14 of said housing. Bothhoning pads may be fastened to their respective support by adhesivebonding or any other applicable means. The layers 77 and 78 are arrangedto touch each other under la predetermined pressure in order tofacilitate the honing procedure.

The materials -for both pads may be leather or other suitable materials,preferably rubber. The abrasive layers |may be made from aluminum loxideor other materials suitable for the honing process.

The rear guard 86, having about the length of the blade 21, ispositioned, and secured by rivets 87 on top of the housing v13, and isproviding a slot 89 between the front edge 88 tof said rear guard andthe blade 21 to facilitate :free rotary movement of said blade. In itstransverse view the guard 86 is shaped to conform with the semi-circularupper portion of the housing `13. v

The storage case consists essentially of the receptacle 101 iand thecover 102, the latter pivotally connected to the rear por-tion offsaidreceptacle by means of pin 107. A resilient latch 10Sy is provided atthe front portion of the receptacle 101 to'coact with the hook 109 as anintegral part lof thev cover 102, to secure the latter in closedposition. 'Ilhe cover 102 may be released by simply depressing the latch10S.

Internally the receptacle `101 is provided with supports and 1-11, :andthe cover l102 with the supports 112 and '113, all said supportsconforming to the respective external configuration olf the razor 10ygiving said razor a inm position when it is placed in said receptacleand said cover closed.

The side wall 114 of the receptacle 101 is provided with the bushing 115to support the spindle 105 for rotation. One end tot the spindle y105 isextending to the inside of the receptacle 101 and is provided with afork or claw v106, adapted to coact with the male part 1S ot the clutch33 of the razor 10. The opposite end 116 of the spindle 105 is projectedexternally, and is provided with the ratchet wheel l117 and crank 103,the hub 118 ot which is slid over the hub 1,19 of said ratchet wheel,and said ratchet Wheel and said crank are 'fastened together with pin120 to the spindle 105. A pawl k121 shown in FIG. 13, is positioned tonthe external face of the side wall 114, and by the actionfotf thehelical spring 122 is coacting with the ratchet wheel 117 to permitrotation of the crank 103 in `only one dinection, i.e. clockwiserelative to the storage case. Handle 104, serving to operate the crank103, tor storage reason, may be tur-ned into the position as indicatedby the phantom lines shown in rFIG. 12.

The external configuration of the storage case 100 is roughly simulatingthe shape of the razor 10, and is provided with handle 1123` for holdingsaid storage case conveniently during the honingprocedure.

When -it is `desired to sharpen the blade 21 in the razor 10, it ismerely necessary to place said razor properly into the receptacle y101of the storage case 100, automatically engage the male part r18 of theclutch 33 of said razor with the claw 106 of the spindle 105, which issupported in the side Wall 114 of said receptacle, close the cover 102`of said storage case, and to turn the crank 103 ot said receptacle a ewtimes. By turning the crank 103, the arresting pin 69 of the clutch 33,coacting siidingly with the opening 52 of the side wall 26 of the bladecarrier 20, rotates said blade carrier with the blade 21 mounted on it,and the tracer pin 51, secured to said side wall, under the effect or"the compression spring `65, rides `on the sine-wave-type cornugated cam68, rforcing said blade carrier with said blade into axially oscillatingmotions, thereby achieving a combined rotaryaxially oscillating movementof the blade 21 between the abrasive layers 77 and 78 ot the resilienthoning pads 22 and 23, the cutting edge 17 trailing the motion of saidblade to produce a honing effect on said cutting edge, known by thetrade as superiinishing process. By selecting the correct abrasivematerials tor this process no material removal will take place duringthe honing cured on the rear of said housing; and means to rotateprocess, justifying to refer to the blade 2l as a permasaid bladecarrier.
